RD52.1-4B-018-L-V1-G3-T1-FW

The Bosch Rexroth Indramat RD52.1-4B-018-L-V1-G3-T1-FW from the RD 500 Drive Controllers series is a high-performance AC Drive Converter designed for industrial automation. This converter with a built-in brake chopper operates at a nominal connecting voltage of 3 x AC 380-480 V and delivers a rated power of 18.5 kW with field-oriented vector control. A forced air cooling mechanism cools the power section from the rear, requiring 0.05 m³/s airflow for optimal heat dissipation. The drive also supports 24 V standby power to maintain control circuits during shutdowns.

Reliability and performance are strengthened by a rated motor output of 15 kW at an 8 kHz pulse frequency and an output frequency range of 0–500 Hz. Continuous duty at 30 A rated output current is complemented by peak current ratings of 39 A (60 s), 51 A (1 s), and 60 A (0.5 s), ensuring torque surges are handled without derating. The unit sustains 26 kVA output power for 60-second intervals and complies with environmental class 3K3 per DIN IEC 721-3.

Engineered for harsh environments, the RD52.1 ensures protection class IP20 and operates reliably between 0 °C and 40 °C with a power loss of 0.63 kW under load. Weighing just 11.3 kg, it integrates an operator panel for local commissioning, while Bosch Rexroth’s RDwin software offers PC-based setup and diagnostics. Installation and operation are reserved for trained personnel, and each unit ships globally with a one-year warranty from Wake Industrial.
